Calibration and adjusting software for Fluke 55xx benchtop calibrators

  • Calibration and adjusting software for Fluke 55xx benchtop calibrators

A universal, professional, automated closed-loop calibration system for METRAHit multimeters can be set up with METRAwin90-F, an IEEE 488 interface at the PC and a Fluke 5500A, 5520A or 5700A calibrator.

However, it’s also suitable for universal use involving the calibration of analog and digital multimeters, recorders, power meters, power measuring transducers, amplifier modules, transducers etc.

Calibration procedures are created with METRAwin90-F. The specified analog values are transmitted via the IEEE 488 interface from the PC to the calibrator and are fed to the device to be calibrated from the analog output at the calibrator. A BD232 adapter is coupled to the computer via an RS 232 cable for automatic transmission of measurement results from the METRAHit multimeter to the computer. In the case of measuring transducers, the analog output value from the device to be calibrated is measured by a METRAHit multimeter, and is returned to the PC for evaluation via the interface. If the measurement results remain within the specified tolerances, each consecutive calibration step is initialized automatically until the entire procedure has been run step by step.

Your advantages

The above mentioned calibrators are used primarily for the calibration of indicating measuring instruments such as multimeters, laboratory recorders, current clamps, panel-mount measuring instruments etc., and include the various electrical quantities required to this end. By incorporating a separate METRAHit 18S, 28S, 29S, 30M, X-TRA, EXTRA or ENERGY precision multimeter with infrared interface into the calibration system, automated calibration of buffer amplifiers, isolating transformers, measuring transducers and the like can be performed.

The software executes interactive (DIRECT operating mode) or sequence-controlled (TEST operating mode) setup of the calibrator from the PC via an IEEE 488 interface, automatic analysis of measured values entered manually or read in from the multimeter via an RS 232 port, and documentation and archiving of calibration results in a calibration report. The program calculates the test uncertainty ratio (TUR) for each calibration point based upon the calibrators’ accuracy specifications which are integrated into the software, or overall measuring uncertainty in accordance with directive DKD-3 (WECC 19-1990).

A calibration procedure for the respective calibration object can be generated and tested in an uncomplicated fashion. Tested calibration procedures for numerous multimeters from our current and previous product spectrum are included with the software.
